means for heating the body of gasolene inthe reservoir by passing heatedgas through a pipe therein, thereby expanding the body of gasolene andfacilitating the flow of gasolene through the feed-pipe tothe gasgeneratoror vapori'zer.

A further object of our invention is to effect improvements in theconstruction of thegas4 generator or vaporizer.A

In the accompanying drawings, Figure lis partly a sectional View andpartly an eleva- Y tion of a gasolene-gas-generating apparatus'embodying our improvements. Fig. 2 is adetail sectional View of thegas-generator. Fig.

3 is a perspective View of a modified formofvv our invention. Thegasolene-feed pipe 1 leads upwardfro a gasolene-reservoir 2,'V the lowerendofthe 'said pipe being submerged in the body of the: gasolene in saidreservoir, and at the upper end ofthe said pipe is a circular generatingor vaporizing chamber 3,1 the said pipe com-u` municating withthecentral portion of said chamber on the lower side thereof. Thegasservicepipe 4 is coupled topa gas-pipe 5, which' leads from the .upperside ofthe generatingchamber and on which is supported ahori'-v zontallydisposed concavo convex shield 6;-

A needle-valve 7 is disposed in the :pipe 5. A

gas-pipe 8 leads from one side of the Vaporizing or generatingchamber-and;is'provided,

with a needle-valve 9, the pintof'whichis disposed opposite themixing-tube or intake 10, that leads to an annular space 11, formedbetween the outer circular casing 12 and the perforated interior tube13, which constitutes the subiiame-burner 14. Said burner is\di`s posedconcentrically on the feed-pipe 1, the

A drip-cup 18, to contain gasolene forinitially heating the generating apparatus and burner, is supported bythe subliame-burner and disposedA under'thepipe S. Any suitable meansmay be the' gas- A pipe18a1eads'from the gas-service pipe 4 .'throughthebody of gasolene in the reservoir 2. The functionof the said pipe 18 isto ciriculate hot gas Vfrom the gas service pipe through the bodyof thegasolene to heat the latter, expand the'same, and facilitate the iowthereof from the gasolene-reservoir to the generator.V A suitableair-compressor, which is indicated diagrammatically at 19 in Fig. 1,isconnected tothe upper portion of the gasolene reservoir and serves tocompress air 'above the body of gasolene in the reservoir,

andthreby cause the gasolene to be fed to the generator `or vaporizer,as will be understood." The gas-service pipe leads to suitableilluminating-'burners 2l. The operation of our invention is as follows:The generator and subflame-burner being iirst initially'heatedin theusual well-known manlner orin any other suitable manner, the gasolenev'is converted f into A gas l orvapor in the chamber 3 and passestherefrom into the gaslar space in the subflame-burner lformed betweenthe outer casing 4thereof and the perforated tube 13. y, As Ythe gas isdischarged 'through the'mixing-jtube into thesubiiameburner.,whichfsurrounds the feed-pipe 1 it is eommingled withair and rendered combustible and on being ignited dischargesra ,plu-

.rality of jets inwardly against the'upper portion of the pipe 1,thereby heating-the said pipe, and as the generating-chamberfisdirectlyabove the subflame-'burner said generating-chamber is also directlyheated on its lower side, the upper side of said generatingchamber beingheated by radiation from the Shield 6.

In Fig. 3 of the drawings we show a modified form of our invention, inwhich the reservoir is a vertically-disposed tank having a false bottom2 ata suitable distance from the lower end thereof. The generator andsubflame-burucr are placed on one side of the tank and at a point lowerthan the false bottom 22 and the feed-pipe l leads downward from thebody of gasolene to the generator, the weight of the body of gasoleneand the hydrostatic pressure thereof being utilized in feeding thegenerator. In this form of our invention the tube 1Sa (shown in Fig. l)is dispensed with, and the service-pipe fi leads from the generator intothe tank and upward through the body of gasolene or other liquidhydrocarbon therein and its heat utilized to raise the temperature ofthe body of liquid hydrocarbon, as will be understood.

While our improved apparatus has been hereinbefore described asefficient in generating gasolene-gas for illuminating purposes, it willbe understood that the gas generated thereby may also be used forheating and cooking purposes in common wood or coal stoves.

'llhe shield 6, in addition toits function in reflecting heat downwardon the vaporizingchamber, prevents the :ignition of the gas from thesubaine-burner.

Having thus described our invention, we claim- 1. In a gasolene-gasgenerator, the combination of a generator, a feed-pipe leading thereto,a subliame-burner in operative relation to said generator, a shield overthe latter, and a service-pipe having its inner end disposed oppositethe discharge of the generator and above said shield, substantially asdescribed.

2. The combination of a generator, a reser voir for gasolene, afeed-pipe leading from said reservoir to said generator, asubflalneburner disposed under the generator, a shield above the latterand through which the vapor discharge of the generator passes, and aservice-pipe, having its open, inner end disposed above said shieldopposite and above said vapor discharge of said generator, saidservice-pipe passing through the body of gasolene in the said reservoir,substantially as dcscribed.

In testimonythat we claim the foregoing as our own we have heretoaffixed our signatures in the presence of two witnesses.
